CY7C1351G-100AXC

Memory IC Overview

The CY7C1351G-100AXC is a 4-Mbit (128K × 36) synchronous flow-through SRAM featuring NoBL architecture. It operates at a maximum clock frequency of 100 MHz with an access time of 8.0 ns. The device supports a 3.3 V core voltage and 2.5 V or 3.3 V I/O supplies. It utilizes a common I/O interface within a 100-pin TQFP package.

Memory IC Feature Summary

• Supports unlimited true back-to-back read/write operations without wait states
• Internally self-timed output buffer control eliminates the need for external OE usage during writes
• Provides byte write capability to simplify read/modify/write sequences
• Includes asynchronous sleep mode for power conservation while preserving data integrity

Memory IC Applications

• Systems requiring frequent write-read transitions
• High-throughput data processing applications
• Backbone memory interfaces in networking equipment

Memory IC Procurement Notes

Verify that the ZZ pin is externally connected to ground as specified in the errata section. Confirm the specific speed grade matches system requirements, as the -100 suffix denotes 100 MHz operation. Ensure the I/O voltage supply aligns with the selected 2.5 V or 3.3 V configuration.

Memory IC Selection Notes

Select this component when zero-wait-state performance is critical for pipeline efficiency. The NoBL architecture distinguishes it from standard synchronous SRAMs by allowing consecutive operations on every clock cycle. Consider the 128K x 36 organization for wide data bus requirements.

Memory IC Part Context

This part belongs to the Cypress NoBL family, now under Infineon Technologies. It is functionally equivalent to ZBT devices but offers superior throughput for mixed read/write workloads. The product maintains continuity with original Cypress ordering codes.

Memory IC Replacement Considerations

NoBL architecture provides distinct performance characteristics compared to standard synchronous or ZBT SRAMs. Direct pin-compatible replacements may not offer identical zero-wait-state capabilities. Verify timing parameters carefully when substituting.
